Abstract

The embodiment of the invention provides a data fusion and flight mode switching method and device for flight equipment. The data fusion method for flight equipment includes: acquiring the measured data of each sensor, determining the work state of each sensor, and performing data fusion according to the measured data and work state of each sensor, thus obtaining flight state variables of the flight equipment and effectiveness parameters thereof. According to the invention, when a disturbed sensor or broken-down sensor exists among the sensors, by determining the work state of each sensor andperforming data fusion according to the work status, measured data of normally operating sensors can be obtained, and through data fusion of the obtained measured data, the flight state variables of the flight equipment and effectiveness parameters thereof can be obtained, thus avoiding error of the data fusion result, realizing safe and autonomous flight of the flight equipment, and reducing theprobability of air crash.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a method and device for data fusion and flight mode switching of flight equipment. Background technique [0002] With the rapid development of flying equipment, flying equipment can already realize autonomous navigation and positioning. The flight equipment usually uses the data collected by various sensors carried by itself to carry out autonomous navigation and positioning. Specifically, the data collected by various sensors is generally fused, and then the flight status of the flight equipment is determined according to the fusion results, that is, The attitude, velocity and position of the flying device relative to the inertial coordinate system. [0003] In the prior art, the model adopted by the data fusion method is established based on the data collected by each sensor when it is not disturbed and has no faults. However, during the flight, each sensor is extremely sus...
